Abstract
A glass/plastic laminate useful in glazing applications which has improved optical quality is provided by controlling the incidence of optical defects induced during manufacture by particulate contaminates by applying a soft plastic film to the outboard side of the plastic surface of the laminate and entrapping such contaminates during the lamination process in the soft plastic film.
